Abstract
The influence of temperature and temperature fluctuations on the pollen germination of different cultivars of apple, pear and Malus were examined.
In 1981, 21 apple cultivars, 14 pear cultivars and 9 Malus cultivars were examined at continuous temperatures of 5 °C, 10°C and 20°C and at temperatures fluctuating from 5 to 10°C and from 5 to 20°C. In 1983, 27 apple cultivars, 11 pear cultivars and 9 Malus cultivars were examined at continuous temperatures of 4°C and 20°C and at 4°C followed by 20°C.

For some regions, it can be very useful to plant pollinator cultivars with high pollen germination vigour at continuous low or temporary low temperatures.
